Specification of Letters Patent.

Patented Jan. 30, 1917.

Application filed March 10, 1916. Serial No. 83,217.

To all whom it may concern:

Be it known that I, EDWARD FISHER, a

citizen of the United States, residing at Newport, in the county of Newport and State of Rhode Island, have invented certain new and useful Improvements in Can and Jar Closures, of which the following is a specification.

This invention relates to devices for closing and sealing the openings in cans, jars, or similar receptacles and has for its objects to provide a simple and eflicient closure for such receptacles.

Devices of the character to which the present improvements relate obviate the dangers following from the practice of opening cans by the use of a can opener or like tool. As is well known the slipping of such tools frequently results in the operators hand being cut by the rough edge of the can top, which may cause a dangerous wound.

The nature of the present invention will best be understood from the following description, when the same is considered in connection with the accompanying drawings, in which,

Figure l is a plan View of a can top with the cover in position thereon; Fig. 2 is a plan view of the can top, with the cover removed; Fig. 3 is an enlarged, sectional view of a can or vessel with parts removed at the center, illustrating the present invention, and Fig. 4 is a plan view, reduced in size, with the sealing cord omitted and the catches indicated by dotted lines.

The can 2, or other vessel, as herein shown is provided with the usual bottom 4, and a top 6, said parts being connected to the can body by a double seam, or in any other desired manner. The top 6 of the can is provided with a downwardly extended annular flange 8, which has a vertical wall of appreciable depth and terminating in a laterally curved, upturned portion 13, and at diametrically opposite points the curved portion 13 is cut out to form the notches 12, 12. The cover 10 of the can is in the form of a disk or plate, and as herein shown has a central depression 16 to receive a pivotally attached bail or handle 21. The cover 10 is also provided circumferentially with a downwardly extending flange 11 having a vertical wall of appreciable depth and terminating in a laterally and upwardly curved portion 9, and is shaped to fit tightly within the upwardly curved flange 13 of the top 6. The cover is also provided with two diametrically located right-angular shaped lugs or catches 17, 17. When the cover 10 is placed upon the can top the laterally and upwardly curved portion 9 of flange ll'fits tightly within the curved flange 13 of the top, and the lugs 17 pass through the notches 12, so that when the cover is turned the lugs will be moved out of register with the notches, and will firmly lock the cover to the can top and prevent its removal therefrom. The laterally and upwardly curved portions 13, and 9 of the can top and cover form a double-walled groove, and, besides effectually resisting inward movement of the top, materially assist the sealing substance inserted in the groove in forming an air tight closure.

In order to seal the contents of the can I provide a cord 18 which is preferably soaked in paraflin, or some other harmless sealing material, to soften the cord, and the latter is then rolled tight and forced into the groove formed in the top of the can above the curved flange 9 of the cover, as clearly shown in Figs. 1 and 3. The cord 18 may be provided with a tag 20, which is fastened to the outer end of the cord and serves as a handle for removing the same from the can top, preliminary to the removal of the cover from the can.

By this invention it will be seen that a very simple and efficient connection is secured between the cover and the top of the can, as the joint formed between the curved flanges 9 and 13 is a very close joint, and the groove in the can top formed by the downwardly extending, interlocking curved flanges on the top and cover, provide for the insertion to a sealing cord by means of which an air tight joint may be formed and the contents of the can or vessel thereby preserved.

While the above described means are shown as applied to a metallic can, it is to be understood that they are equally applicable to other kinds of vessels, as, for example, glass jars and the like.

Changes may be made in the form, construction, or minor details of the parts herein shown, without departing from the spirit of the invention.
